"Tom Izzo is a great tournament coach," Obama said. "I've got Michigan State going all the way. ... He knows how to motivate folks and he knows how to coach. My pick: Michigan State. Bring it home for me. It's been a while since I've won my pool."

It's the sixth time ESPN has gotten the president to share his choices. He's correctly picked the winner once. The network recaps his track record as a prognosticator: "Obama has picked three different teams in the 'Barack-etology' era to win the men's title — Indiana (over Louisville in 2013), Kansas (over Ohio State in 2011 and Kentucky in 2010) and North Carolina (over Kentucky in 2012 and Louisville in 2009). His correctly picked national champion was the Tar Heels in '09."

Filling out brackets, by the way, is a bipartisan passion. Sen. John McCain of Arizona, Obama's Republican opponent in 2008, has again posted his picks. Perhaps not surprisingly, he ends up with the University of Arizona as champion.
